Well above is the show stopper. Those of us who voted for Bush or those of us from states that went Bush in 2000 are by implication "Intolerant." Why would you seriously consider the views of someone with this kind of bias.
Larry Sabato is biased, before Wellstone passed away, he used to say he was "refreshing breath of fresh air". However, he also is generally around the mark, not exact, He got the 2002 senate races slightly off, but he's kind of close, and does use good reasoning to come up with his numbers.
That said, close, and a couple of quaters, will get you a cup of coffee, and nothing else.
